Japanese Chinese immigrants

First of all, Japan is not an immigrant country. If you have lived in Japan for five years and have a formal tax payment record of more than three years, you can apply for naturalization (as a regular employee in a Japanese company). In addition, you can apply for permanent residence if you have lived in Japan for 10 years and have a formal tax payment record of more than 5 years. (It is more difficult to become a regular employee in a Japanese company) or marry a Japanese. Generally, you can apply for permanent residence or naturalization three years after giving birth.
